Pale Moon is an Open Source, Firefox-based web browser for Microsoft Windows, focusing on efficiency and ease of use. Make sure to get the most out of your browser!

Pale Moon offers you a browsing experience in a browser completely built from source with carefully selected features and optimizations to maximize the browser's speed*, stability and user experience, while maintaining compatibility with the thousands of Firefox extensions you have come to love and rely on.

This browser, even though close to Firefox in the way it works, offers a different set of features than its sibling. A few carefully selected features have been disabled that are not in high demand, and that do not interfere with the way web pages are displayed or function; all to maximize the efficiency of the browser. Please see the page with technical details to learn exactly what the browser supports, and what it doesn't support. For example, if you need accessibility features or parental controls, then please visit the Firefox homepage and get the official, non-optimized version of the browser.

With the current generation of Gecko-based browsers, there are a few other differences between Pale Moon and Firefox that are more obvious and not just "under the hood": contrary to what Mozilla has done with their redesign of the user interface, Pale Moon will continue to provide a familiar set of controls and visual feedback similar to previous versions, including grouped navigation buttons of a decent size, a bookmarks toolbar that is enabled by default, tabs next to page content by default (easily switchable) and not in the least a functional status bar, to name a few things.
